What happens when the jade bracelet turns off the light and turns yellow when the purple light is tu

The fluorescence illuminated by the violet lamp is calcium and phosphorus, rare earths.

Phosphors are usually divided into two categories: photoinduced energy storage luminous powder and radioactive luminous powder. Photoluminous energy storage luminous powder is a phosphor that stores light energy after being irradiated by natural light, daylight light, ultraviolet light, etc., and then slowly releases it in a fluorescent way after stopping light irradiation, so it can still see the luminescence at night or in a dark place, and it lasts for several hours to more than ten hours. Luminous powder with radioactivity is mixed with radioactive substances in phosphors, and the rays emitted by radioactive substances are used to excite phosphors to emit luminescence, which luminous powder has a long luminous time, but because of toxic and harmful and environmental pollution, it is more cautious in application.

Ultraviolet. Below, the jadeite is yellow, and there is no fluorescence reaction, indicating that it is a goods. After the jadeite is polished, the polishing powder enters the crack, and the cracked part will have a fluorescent reaction, which is a normal phenomenon.

Can a purple light hair dryer be used to shine on a jadeite bracelet Purple violet light can verify the authenticity of jadeite. When purple light irradiates jadeite, natural stone has no fluorescent reaction, real jadeite will not glow, and fake jadeite will produce a strong fluorescence reaction after a certain degree of chemical dyeing. However, when the surface of the real jadeite is waxed and mixed with stone impurities, violet light irradiation will also produce a small amount of fluorescence.

Before identifying the authenticity of jadeite, the surface of jadeite needs to be cleaned to avoid too much wax on the surface and affect the judgment of authenticity.

There is no yellow, this is also a jadeite A goods, it is a little bit of polishing powder residue, it does not have much impact, it will fall off after wearing it for a long time, rest assured to wear it, just like it.

Look** is a jadeite A goods (that is, really) there is no problem.

Bean seed jade bracelet, poor water, belongs to low-end goods, and has little value.

Emerald bracelet in purple light.

There is a fluorescence reaction under it, which is usually recognized as B cargo jadeite, but there are several cases of A cargo jadeite.

There will also be some fluorescence reactions, such as polishing powder residues, as well as the optical phenomenon of white jadeite, etc., polishing powder residues, which are produced by violet jadeite in the polishing process. In this process, if there is a purple polishing powder remaining, then, in the ultraviolet lamp.

There will be a fluorescence reaction, this reaction, in fact, you can see on the jade bracelet certificate, there is such a note "polishing powder residue", followed by "stone impurities", the probability of this situation is very small, such a jade bracelet is also a genuine jadeite. It just hasn't undergone any treatment, this jadeite is mixed with too many stone impurities, and it is precisely because of these stone impurities that this jade bracelet fluoresces under the ultraviolet lamp. The chances of this happening are very small.

Hello, it will. There are two reasons why jadeite bracelets fluoresce under violet light, firstly, it has a lot to do with the particle structure inside it. Just like the ice jadeite, its particles are delicate and evenly arranged, and when the light passes through, it will form a hazy white spot, and from the naked eye, it is the hazy white light transmitted from the inside of the jadeite.

Secondly, when you buy dyed fake jadeite, it will fluoresce under the irradiation of the violet lamp, but this kind of jadeite is generally worthless.

The phenomenon of purple light in the jadeite bracelet under the fluorescent lamp is because the iron and chromium contained in the jadeite will resonate and absorb under the excitation of purple light. This phenomenon is known as "immersion resonance" and is a unique physical property of jadeite.

When ultraviolet rays or fluorescent lamps irradiate the iron and chromium elements in the jadeite, these elements will absorb purple light, and then through the defects and cracks inside the crystalline body of the jadeite, various forms of crystal defects will occur, and many reflections and dispersions will occur, and finally the phenomenon of purple will be formed.

Therefore, when we see jadeite showing a beautiful purple light under the fluorescent lamp, we are actually appreciating the unique physical properties of jadeite. However, it should be noted that this resonance phenomenon does not affect the quality and value of jadeite, but is just a natural optical phenomenon.

Jadeite is a very precious gemstone, and purple light is a very special phenomenon among gemstones. If the jadeite bracelet glows purple under a fluorescent lamp, it may be because the jadeite middle finger is noisy and contains chromium.

Jadeite is usually composed of green minerals, and the presence of chromium can make the green in the minerals more saturated, resulting in a more beautiful green color. At the same time, chromium can also give minerals a purple or blue sheen under certain lights.

Therefore, when the jadeite bracelet glows purple under the fluorescent lamp, it may be because the jadeite contains chromium, and the light in the fluorescent lamp is just enough to excite the chromium in the jadeite, giving it a purple sparrow luster. This phenomenon is more common in jadeite and is one of the beautiful features of jadeite gemstones.

The jadeite bracelet is a little purple under the light because the jadeite has been treated.

This technique first appeared in Hong Kong in the late 70s and early 80s of the 20th century, which dealt a serious blow to the jadeite trading market. The purpose of the treatment is to remove the dirty color (mainly yellow, black, gray and other colors) through pickling, improve the germplasm, cover up the cracks and smiles, and improve the appearance.

Steps to deal with jadeite:

1. Material selection. Generally, the number of ridges is to select materials with loose structure, coarse grains, poor quality, and secondary cherry blossom color, dirty color, which affects the color of the jadeite itself.

2. Cutting. In order to make pickling and glue filling more adequate and fast, cut large pieces of raw materials into jade pieces or jade rings of a certain thickness according to the use.

3. Pickling and bleaching.

The main varieties of acids are: nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid, etc.

Pickling time: The time varies according to the different jadeite germplasms, about 2-3 weeks, or even several months.

4. Alkali washing neutralizes and increases gaps.

Strong alkali corrosion, the purpose is to further increase the pores of jadeite and neutralize the acid in the pores. Because the residual acid in some pores is not conducive to glue filling. It needs to be heated and soaked with sodium hydroxide, and the alkali and silicate react to corrode, increase the pores and voids of jadeite, and neutralize the acid in the sub-gaps.

Pickling and alkali washing seriously damage the structure of jadeite, resulting in the combination between jadeite particles becoming loose and the strength being destroyed. If it is destroyed and slag-like after alkali washing and bleaching, it can be crushed by hand, and it becomes a waste product. <>

Summary. 1. After the natural high-quality jadeite is treated with sealing wax, the residual wax shows a dotted fluorescence.

Second, the B and C goods of jadeite fluoresce as a whole under the violet lamp, and third, other identification methods of jadeite:

1. Look at the luster of jadeite.

The jadeite is vitreous, the reflective surface is as bright and sharp as glass, and the reflective points are concentrated and do not diverge. Jadeite, with high transparency and strong vitreous luster, is a popular variety of high-quality jadeite. The luster of B and C jadeite is not strong, similar to the luster of oil, and it is not as bright as A goods.

2. Look at the white cotton of jadeite.

White cotton refers to the translucent, slightly transparent white substance of jadeite that is patchy, banded, filamentous, and corrugated inside. Although the presence of white cotton more or less affects the beauty of jadeite, it is also one of the identification methods of jadeite, and the white cotton of jadeite also reflects the natural nature to some extent.

3. Look at the hardness of jadeite.

The hardness of jadeite is relatively high, it can easily cut through glass, and the toughness is also very high, and it will not break easily. The hardness of jadeite after artificial treatment will decrease, and the hardness of jadeite is not as high as that of A-goods.

The purple light hits the jadeite and it is yellow.

Hello kiss, I'm your answer specialist I'm helping you answer your questions Please wait a moment It takes time to type.

The jadeite hits the purple light and turns yellow-green jadeite under the purple light.

If you are satisfied with my answer service, remember to give a thumbs up, thank you, I wish you a happy life.

What is this. Kiss you poor silver is late, under ultraviolet light, jadeite yellows and has no fluorescent reaction, which means that it is a goods. The jadeite is polished by the virtual plum, and the polishing powder enters the crack, and the cracked part will have a fluorescent reaction, which is a normal phenomenon.

It feels a little yellow to the naked eye, but it doesn't come out, so it's my eye problem.

Hit the purple light.

1. After the natural high-quality jadeite is treated with sealing wax, the residual wax shows a dotted fluorescence.

Second, the B and C goods of jadeite fluoresce as a whole under the violet lamp, and third, other identification methods of jadeite:

1. Look at the luster of jadeite.

The jadeite is faintly vitreous, and the reflective surface is as bright and sharp as glass, and the reflective points are concentrated and do not diverge. Jadeite, with high transparency and strong vitreous luster, is a popular variety of high-quality jadeite. The luster of B and C goods jadeite is not strong, similar to the luster of oil, and the leakage resistance is not as bright as the return of A goods.

2. Look at the white cotton of jadeite.

White cotton refers to the translucent, slightly transparent white substance of jadeite that is patchy, band-like, silky noisy and corrugated. Although the presence of white cotton more or less affects the beauty of the jadeite, it is also one of the identification methods of jadeite, and the white cotton of jadeite also reflects the natural nature to some extent. Grilled dates.

3. Look at the hardness of jadeite.

The hardness of jadeite is relatively high, and it can easily cut through the glass, and the toughness is also very high, and it will not break easily. The hardness of jadeite after artificial treatment will be reduced, which is not as high as the hardness of jadeite of A goods.

Related information: jadeite bracelet has a fluorescent reaction under the purple lamp, indicating that it may be B jadeite, which is a product that uses natural slag jadeite rough for post-artificial treatment, and its essence is still jadeite raw materials, just because its texture is not good enough, and some impurities are more, and the merchant beautifies it in order to achieve the purpose of sales. There is another situation that some kinds of coarse white jadeite will reveal purple light under the irradiation of the purple lamp, which is not necessarily a fake, but because the white jadeite is more likely to reflect, and the purple lamp itself has purple, and it will shine on this jadeite with purple light.

Under the violet light, the jadeite has a fluorescence reaction caused by chemicals, indicating that it has been artificially processed. It was originally an inferior jadeite, and its properties were artificially changed by methods such as dyeing, glue injection, soaking Liang's wax or using polishing powder, which is what experts say about B goods. Put the jadeite under a fluorescent lamp and observe its color change, A and C will not change, while only B will fluoresce and white.

Fluorescence refers to the phenomenon that gemstones emit light when excited by external energy (ultraviolet rays, etc.), and the luminescence stops immediately after the excitation source is withdrawn, and this luminescence phenomenon is called fluorescence.
